Hello hissho,
I agree with Wayne’s comments above. Each position has trade offs, and there are usually risks and rewards associated with any position. Sometimes there are low risk arbitrage positions that can occur from anomalies in the market, but these are rare, and often snapped up by professional organisations that specialise in this area. Hence I’m very sceptical on the concept of a “perfect position”. My response below is aimed at the generic approach of using synthetic strategies, and not a comment on this particular case.
You are correct in your options theory question about the shape of the risk graph (POD) for this synthetic, in that it resembles a long call. There is a portion of the risk graph that represents a limited loss. This is theoretically the maximum loss, then add the associated transactions costs on top.
With synthetic positions there are some variables to consider. Firstly, this kind of longer term strategy works best in a strongly up trending market, and requires the stock selected has sufficient projected growth and dividends to make it an attractive consideration. This will also depend on an assessment of where the market is likely to move – essentially if the bull market will continue, or a correction is likely should form part of the rationale.
The notion of gearing shares in synthetic positions begs the questions as to how to do this. If a position is on margin, then there are associated costs and risks involved that should be considered. There may be an ongoing interest component for instance, and the amount borrowed may vary affecting the potential risk.
If the underlying moves bearishly and the puts are not correctly matched to the underlying, there can be losses above the entry and exit transaction and associated costs. If the puts were sold since they gain value in a bearish move, unknowns like volatility and spread risk can adversely affect the outcome too, not to mention how far into the money and what the delta and gamma may look like at exit. Exercising the puts while they still have time value may cause a loss to of this component, as opposed to selling them.
The key point here is that when a position is leveraged heavily, there should be a consideration of the real exposure to loss, which could actually be quite substantial because of the magnitude of the position.
If an investor borrowed half of a $1 million position, they will be exposed to $500,000 risk if the stock went to 0. Sure, this is unlikely, but the margin has been borrowed, and must be paid back, plus the position is accruing interest against this amount. If the matching of the puts is wrong, consider the potential for error involved with a $500,000 loan which is owed, and even a small percentage of this can result in a loss that may be considerable.
If long term investment style warrants which yield dividends are used in place of shares on margin, these also have time value costs associated incorporating interest rates, and spread slippage (Wayne refers to this and brokerage as “contest risk”). The model for matching puts to these kinds of leveraged positions is complicated, and the models often have irregularities depending on time, direction, and magnitude of the underlying price.
Also, Warrants are OTC instruments, and conditions may vary, and there is credit risk involved in these instruments.
Hope this helps.
